From the Munich crisis to the dropping of the first atom bomb, and from Hitler's declaration of war on the United States to the D-Day landings - historians suggest "what would have been" if key events in the war had gone differently. Written by an exceptional team of historians as if these world-changing events had really happened, realistic scenarios based on the true capabilities and circumstances of the opposing forces are projected with chilling implications. What if the Nazis had taken London? The alternate outcomes are fascinating and fully realized.
